Description

• We would like to create a routing rules for existing route tables, however there is no existing terraform oci module for resource routing routes.
• This option will give developer's option to separate the code for route table and it's rules.
• This will be helpful for changes in additional routes in selected route tables without affecting the route table and existing routes associated with it.
• DRG has this module, we wish to have it in oci_core_route_table as well.
